Homogeneous and Heterogeneous metal-catalysed isotopic hydrogen exchange in alkylbenzenes. Mechanism of alkyl deuteriation in ethylbenzene
Abstract
Homogeneous and heterogeneous metal-catalysed isotopic hydrogen exchange in the alkyl group of [β-14C]ethylbenzene shows that predominant deuteriation does not occur via previously suggested mechanisms involving reversible dealkylation or carbonium ion intermediates: instead a π-allylic process is suggested.
